The base includes a bottom plate and a support plate which are hinged to each other at one end; the bottom plate and the support plate form an acute anglewith each other; the bottom plate and the support plate are respectively provided with a through hole used for penetrating an anchor cable; one side of the bottom plate away from the support plate isprovided with a friction structure for increasing friction; and an angle adjusting device is disposed between the bottom plate and the support plate; and the angle adjusting device includes multipletooth form grooves respectively disposed on opposite sides of the bottom plate and the support plate, and further comprises an adjusting wedge with two ends respectively snapped to one of the tooth form grooves. The anchor cable base adjusts an angle between the bottom plate and the support plate by the angle adjusting device, an anchorage device is kept to be parallel to an opposite surface of the support plate, so that the force direction of the anchor cable is perpendicular to the support plate, and so, in a tensioning process, a shearing force is not generated on the anchor cable due to anincluded angle existing between the anchorage device and the anchor cable, the anchor cable is prevented from being cut due to extrusion, the accuracy of a tensioning force is ensured, and the anchorcable base is used in the field of soil protection.
